HARRY A. WHEELER, 0F WHITMAN, MASSACHUSETTS.

TAPE-PASTING MACHINE.

To all whom it may concern:

Be it known that I, HARRY A. WHEELER, a citizen of the United States, of Vhitman, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Tape-Fasting Machines, of which the following is a specifcation.

This invention relates to pasting machines, and more particularly to tape pasting machines, that is, machines for applying an adhesive, such as cement, paste, or a similar substance to tape or the like.

One object of the invention is to provide a machine for applying an adhesive, such as cement, by means of a rotary 4carrier to tape such as is used in the manufacture of shoes and to prevent t-he evaporation of the volatile solvent of the cement.

A further object of the invention is to provide a machine with mechanism for applying an adhesive to a strip of tape as it is drawn through the machine, the act of drawing the tape through the machine causing the adhesive applying mechanism to rotate and apply the adhesive to the tape.

A further object of the invention is to provide a machine for applying an adhesive to tape, said machine having a rotary carrier for raising the adhesive from the adhesive reservoir and applying it to the under side of the tape, the friction of the tape upon the carrier operating to rotate the latter, and means for varying the degree of pressure between the tape and the carrier.

A further object of the invention is to provide an adhesive applying machine having a corrugated adhesive-applying wheel for conveying the adhesive from the adhesive receptacle to the t-ape and applying it thereto, a device for guiding the tape upon the wheel and varying the degree of pressure between the tape and the adhesive carrier to accommodate tapes of various thicknesses and widths, and also means for stripping any surplus adhesive from the periphery and sides of the wheel.

Vith the above objects in view, the invention consists in the improved tape pasting machine hereinafter described and particularly defined in the claims, the advantages of which will be obvious to those skilled in the art from the following description.

The several features of the invention will be clearly understood from an inspection of Specification of Letters Patent.

the accompanying drawings and the following detailed description of the construction shown therein.

In the accompanying drawings Figure l is a top plan view of the machine; Fig. 2 is a longitudinal central vertical section of the machine with parts in elevation and showing the tape passing through the machine; Fig. 3 is a side elevation of the machine; and Fig. 4, is a vertical section taken on the line 4-4 in Fig. 3, with parts in elevation.

As shown in said drawings the machine comprises a sheet metal reservoir 10 for t-he adhesive which is to be applied to the tape. This reservoir is in the form of a rectangular tank having its upper edges flanged to rest upon the upper faces of the frame work or base of the machine. Said tank is adapted to contain a quantity of adhesive 11, such as cement or paste, which is commonly used in the manufact-ure of shoes. The base comprises side standards 12, 13 which are secured to end bars 14, 15 by means of screws, or in any other manner to form a rectangular frame. These standards are arched to make them light and the frame is formed with a fiat upper surface which forms a bearing for the flanged upper edges of the reservoir.

A plate 16 forms the top of the machine and acts as a cover for the reservoir. This plate is removably held upon the machine by bolts 18, pivotally mounted upon the side standards and adapted to enter slots 2l formed in lugs 22 on the cover plate. Knurled nuts 24 are threaded upon the upper ends of the bolts and bear against the upper surface of the cover plate to keep it tightly in position on the machine. In order to correctly locate the cover plate 16 upon the machine, it is provided with holes 17 adapted to register' with dowel pins 19 mounted in the end bars 14, 15 of the base.

The adhesive applying mechanism comprises a wheel 26 projecting through an opening 27 formed in the cover plate 16. Said wheel is provided with fine, shallow teeth or corrugations formed upon its periphery and is mounted upon a shaft 28 j ournaled in bearings 29 depending from the under side of the cover plate 16. The depth of the liquid in the tank is such that the wheel 26 dips below its surface. The corrugations constitute a series of pockets to carry the adhesive 11 from the reservoir to the under side ot the tape and apply it thereto and also aid the tape in rotating' the wheel, as will be hereinatter explained.

it pair et side stripper plates 30 are secured by means oli screws to the upper surface ot the 4plate lo adjacent to the sides o1 the wheel to prevent the adhesive from being carried to the top portion ot the sides of the wheel. :t central stripper' plate is adjustably mounted upon the upper surtace of the plate 1G between the plates 250 by means ot screws E32-5 passing through slots in said stripper plate. rl`hus the stripper plate may be adjusted with relation to the periphery oit the wheel to vary the amount of adhesive carried up by the wheel and applied to the tape. Obviously, other means tor etl'ectinp, the adjustment ot' this central stripper plate may be employed.

rThe tape 3l is ted Jfrom a reel (not shown) through a guide or eye 3G mounted upon the upper side ot the platn 1G. This guide may be ot any Suitable width adapted to .tit the particular size ot tape which is being` run through the machine. From the `guide the tape passes to the periphery of the adhesive ai'iplyingl wheel 9G against which itis pressed by a resilient arm 3S havingY a llat portion or plate 3S) at one end which presses against the tape, and is provided with depending ilanges r-Ll-(l which lie adjacent to the sides ot the wheel and act to guide the tape laterally to properly position it with relation to the periphery of the wheel. The other end' of the arm 88 is secured by means of bolts Ala2, el?) and nuts to the horizontal portion of a bridge plate which is mounted upon the upper side ot the plate l' and straddles the stripper plates 30 and rthe two ends of the arm 38 are o'tl'set vertically relatively to one another an amount slightly greater than the vertical distance between the highest point on the periphery o't the wheel 1G and the upper tace ot the horizontal portion of the bridge plate ist. rhus, by adjusting.;v the nuts -lon the bolts 4t2 and 41:3 the pressure exerted by the arm upon the tape may be varied, and the device adapted to receive tapes of various thicknesses. ln order to more satisfactorily press the plate 39 in contact with the tape Si it has been found advisable in practice to provide a sheet metal spring` ll-( which is held at one end between the upper surface of the arm 38 and nuts 45, and having its other end il? bent to bear against the upper surface oi" the plate 39. rlhis spring may be bent to vary the pressure which it will exert upon the plate 39 when adjusted by means off the nuts rlhe pressure thus exerted by the plate 39 against. the tape and wheel is suthcient to enable the tape to cause the rotation ot the wheel it is drawn over thc periphery oi" the latter in contact with the eorrugations.

ln using` the machine the tape is drawn through the guide 3" and between the wheel 2li and the presserplate 3S. rl`he operator draws the tape toward the 'front or right hand end ot the machine as viewed in the or the volatile solvent employed in cements adapted tor use in cementingr tapes or other materials used in the nuuuitacture ot slices, tor which this machine is primarily intended to be used.
